MoscowAges 45–74 - NCT06341621RecruitingPhase 3
Skipping chemo for ER+/HER2- breast cancer with 1–3 positive nodes
This trial tests whether skipping chemotherapy is safe for women with a specific type of early-stage breast cancer (ER-positive, HER2-negative) that has spread to 1–3 lymph nodes. Instead of chemo, you would receive a targeted pill called abemaciclib after standard hormone therapy.
ShanghaiAges 18–80 - NCT06255392RecruitingPhase 3
Fluzoparib with apatinib vs chemo for advanced breast cancer
This trial tests a combination of two oral targeted drugs (fluzoparib and apatinib) against standard chemotherapy for women with advanced, HRD-positive, HER2-negative breast cancer. It may be an option if you have already received some treatments but not too many.
Guangzhou, GuangdongAges 18–70 - NCT05360290Recruiting
Study checks cancer cells in breast tissue after surgery
This trial looks for circulating tumor cells—cancer cells that may travel in the blood—after standard breast cancer treatment, including chemotherapy before surgery and surgery itself. It may help doctors understand who might be at higher risk and tailor follow-up care.
Shanghai, Shanghai MunicipalityAges 18–70 - NCT06738654Recruiting
Robotic breast-conserving surgery through the armpit for early-stage breast cancer
This trial tests a new robotic technique for removing early-stage breast cancer through the armpit, leaving no scar on the chest. It may be an option for women who want to keep their breast shape and avoid visible scarring.
Chongqing, Chongqing MunicipalityAges 18 years+ - NCT05835739Recruiting
Study of breast cancer prevention in BRCA1/2 mutation carriers
This is an observational study that looks at how different cancer prevention approaches affect women with harmful (deleterious) BRCA1 or BRCA2 mutations. It may help improve future prevention and follow-up plans for women at higher inherited risk.
Aviano, PordenoneAges 18 years+ - NCT06538896RecruitingPhase 2
Tislelizumab and nab-paclitaxel for advanced triple-negative breast cancer with bone spread
This trial tests a combination of two drugs, tislelizumab (an immunotherapy) and nab-paclitaxel (a chemotherapy), as the first treatment for advanced triple-negative breast cancer that has spread to the bones. It aims to see if this combination can help shrink or control the cancer.
Hangzhou, ZhejiangAges 18–70 - NCT05190094RecruitingPhase 2
Test blood-based laser scan to guide first-line breast cancer treatment
This Phase 2 study uses a specialized laser test on a blood sample to predict how well palbociclib plus letrozole or anastrozole will work. It’s for certain postmenopausal women with HER2-negative, hormone-receptor positive, advanced (stage IIIb/IV) breast cancer.

Testing anti-HER2 treatment for HER2-enriched early breast cancer
This trial tests an anti-HER2 medicine in people whose breast cancer is classified as “HER2-enriched” using a special lab test (PAM50). It aims to see whether this treatment can help prevent or control cancer that cannot be fully removed by surgery.
SeoulAges 19 years+ - NCT06595147Recruiting
Exercise for heart health in breast cancer survivors
This study tests if a 12-week exercise program improves heart health in women over 60 who have finished treatment for early-stage breast cancer. You will be placed in either an aerobic exercise group or a stretching group to see which helps your heart more.
Edmonton, AlbertaAges 60 years+ - NCT05879926RecruitingPhase 3
Testing chemo after hormone therapy in premenopausal early breast cancer
This Phase 3 trial checks whether adding chemotherapy after standard hormone-blocking treatment works better for some premenopausal women with early-stage, ER-positive, HER2-negative breast cancer. It targets patients with limited lymph node spread and a lower-to-intermediate tumor “recurrence” risk score.
Birmingham, AlabamaAges 18–60 - NCT05621837Recruiting

MilanAges 18–90 - NCT05872295RecruitingPhase 1
Study drug for HER2-positive advanced cancers
This Phase 1 trial tests IKS014 to see how safe it is and how well it works in advanced solid tumors that have HER2. You may be eligible if your tumor is HER2-positive (including certain “low HER2” types) and your body’s blood counts and organ function are strong enough.
Newport Beach, CaliforniaAges 18 years+ - NCT06636981RecruitingPhase 2
Combination therapy for advanced triple negative breast cancer
This trial tests a new combination of a vitamin A derivative (all-trans retinoic acid), an immunotherapy drug (toripalimab), and chemotherapy for people with advanced triple negative breast cancer that cannot be removed by surgery or has spread. The goal is to see if this combination helps shrink or control the cancer better than current treatments.
